With the full-scale rollout of Japan's cigarette vending machine age-verification system just around the corner, a Sankei Sports news reporter has confirmed the existence of a minor flaw: magazine photos can be used to fool the age-verification cameras on some machines.

When the reporter went to check out the new age-verifying machines after they were introduced in the Osaka area in June, he soon discovered that the machines equipped with face-recognition cameras would let him buy cigarettes when he held up a 15-centimeter (6-in) wide magazine photo of a man who looked to be in his 50s.

The reporter also went to Kobe, where different face recognition hardware is being used. There, he bought cigarettes using an 8-centimeter (3-in) wide magazine photo of a female celebrity in her 30s. He also reportedly tried to use a 3-centimeter (1-in) wide photo, but the machines rejected it.

As part of the age-verification system, most of Japan's 570,000 cigarette vending machines are being outfitted with RFID readers that check the purchaser's Taspo age-verification card. Smokers without a Taspo card can now either buy their cigarettes in person over the counter or use one of 4,000 special machines equipped with face-recognition systems (these machines do not require Taspo cards). More face-recognition machines are on the way, according to vending machine manufacturer Fujitaka, who developed the face-recognition hardware.

The face-recognition machines rely on cameras that scan the purchaser's face for wrinkles, sagging skin and other signs of age. Facial characteristics are compared with a database of more than 100,000 people, and if the purchaser is thought to be well over 20 years old (the legal age), the sale is approved. If the purchaser looks too young, they are asked to prove their age by inserting a driver's license. According to Fujitaka, the machines are 90% accurate.

Fujitaka admits that people may, on occasion, be able to fool the age-verification cameras with photographs -- but only for the time being. The company is now working on a more advanced system that will make sure each face belongs to a real human, but they are unable to say when these new machines will be put into place.

IT company Kayac has teamed up with researchers from Keio University to develop a high-tech brainstorming room that listens to its inhabitants and feeds them a barrage of related data and images in order to boost creativity and fuel the imagination.

The system -- called "Kage Roi" -- relies on a speech-recognition capable computer that monitors the brainstorming session via microphone, identifies keywords, and automatically crawls the web in search of related information and images. A ceiling-mounted projector then casts the retrieved data and imagery onto dark, human-shaped shadows on the table during the course of the meeting. The brainstormers can free-associate on the projected data, use it as a tool for discussion, or rely on it for helpful cues if ideas are running short.

Kage Roi also features an ambient, multi-colored LED lighting system designed to stimulate creativity by altering the mood of the room. The "half-day course" setting, for example, simulates the rising and setting of the sun over the course of a 2-hour brainstorming session, helping to create a gradual mood shift as the meeting progresses.

Kayac developed Kage Roi in cooperation with the Keio University Inakage Lab (imgl), whose research focuses on next-generation digital communication and entertainment. The system was installed in a meeting room at Kayac headquarters last month, and the company plans to begin field-testing it soon.

Kayac hopes to develop a practical version of the system in the near future, and they are considering marketing it to companies in the content creation industry.

Rice-growing season has only just begun, but this year's first crop of rice paddy art, which is created by planting various colors of rice in the field, has already started to emerge.

In the Yamagata prefecture town of Yonezawa, an image of 16th-17th century samurai Naoe Kanetsugu has appeared in a field near the Onogawa hot spring. The samurai, whose image is based on a portrait housed at the nearby Uesugi Museum, appears along with a pair of fireflies and the kanji characters for "Love" and "Tenchijin," the name of an NHK drama about Naoe Kanetsugu that will air next year. The rice will be harvested in October.

This year marks the third time that crop art has been grown in Yonezawa. Here are a few photos of works from the past two years.

In recent years, a growing number of local governments around Japan have started organizing rice paddy art projects as a way to attract tourists and educate people about rice farming. Look for more rice paddy art to crop up in the coming weeks.

Space transportation provider Rocketplane Kistler Japan has teamed up with wedding planner First Advantage to begin hosting weddings aboard the Rocketplane XP suborbital spaceplane. A cool 240 million yen ($2.2 million) buys you a wedding ceremony aboard a 1-hour space flight that reaches an altitude of more than 100 kilometers (62.1 miles), as well as a photo and video album, original dress, wedding certificate and other ceremonial items. The otherworldly price tag also includes the cost of transportation to and from the launch site, accommodations, a live broadcast of the ceremony to friends and family at a reception hall on the ground, and 4 days of rehearsal. The space wedding services are scheduled to begin in 2011, but the group will start accepting applications early next month.

In an unsettling sign of the times, the new "Smoke Block" emergency mask by Tokyo-based Rescuenow, Inc. is being touted as an effective means of protection against hydrogen sulfide, the trendy "detergent suicide" gas created by mixing household cleaners, which has claimed hundreds of lives across Japan in recent months. The mask has a special three-layer filter that keeps your lungs clean for up to 20 minutes, allowing you ample time to flee from smoke and/or toxic fumes. A full-face mask sells for 20,000 yen ($185) and a half-face version goes for 14,000 yen ($130).

Japan's Ministry of Economy, Trade and Industry (METI) has released a few details about the "Zero Emission House," a state-of-the-art green home under construction at the site of the upcoming Hokkaido Toyako G8 Summit, where environmental issues will be high on the agenda.

Incorporating the latest in sustainable building technology, the 280-square-meter (3,000 sq ft) Japanese-style home is designed to have a small carbon footprint. A 14.5-kilowatt solar array and a small 1-kilowatt wind generator provide power to the home, which is equipped with next-generation energy-saving appliances, thermal insulation glass, vacuum insulated panels and a green roof. The interior is illuminated by a system of light ducts and OLED lamps.

Honda's Asimo humanoid robot -- whose exact carbon footprint size is unknown -- will be on hand to serve tea to guests, who are welcome to test-drive the electric vehicles in the driveway and soak their feet in the fuel cell-powered foot bath.

Construction of the 200 million yen ($2 million) home is scheduled for completion at the end of June, at which time it will be unveiled to the foreign press. After the summit, plans are to transport the house to another location, where it will be opened to the general public.
